High resolution laser spectroscopy of relaxation and the excitation lineshape of excitons in GaAs quantum well structures
(Elsevier, 1990-04-01)
A new class of measurements on GaAs quantum well structures based on frequency domain nonlinear laser spectroscopy is described. Room temperature measurements of the excitation relaxation show an interference effect in the ...
Epitaxial growth and characterization of GaAs/Al/GaAs heterostructures
(Elsevier, 1990-04-01)
We report on transmission electron microscopy, secondary ion mass spectroscopy, X-ray and Raman scattering studies of GaAs/Al/GaAs heterostructures grown by migration enhanced epitaxy.
Charge-density domains in photoexcited quantum-well structures
(Elsevier, 1990-04-01)
We present theoretical and experimental results on the dielectric response of an electron-hole plasma confined to a quantum-well. Hartree calculations reveal large nonlinearities in the screening properties which, when ...
